Description
- This application is a continuation of U.S. patent application Ser. No. 12/088,399, which was filed on Aug. 3, 2009 and was a U.S. National Phase filing under 35 U.S.C. 371 claiming priority to PCT Application No. PCT/US2006/048991, which was filed on Dec. 20, 2006, which application in turn claims priority to U.S. Provisional Patent Application Ser. No. 60/755,569, which was filed Dec. 30, 2005, all of which are incorporated herein by reference.
- The present invention relates generally to antibacterial compositions exhibiting the antibacterial effectiveness of quaternary ammonium compounds and reduced irritation to mammalian tissue.
- Antibacterial personal care compositions are known in the art. Especially useful are antibacterial cleansing compositions, which typically are used to cleanse the skin and to destroy bacteria and other microorganisms present on the skin, especially the hands, arms, and face of the user. Several different classes of antibacterial agents have been used in antibacterial cleansing compositions. One such agent, quaternary ammonium compounds, are effective cleansing agents, however, these compounds can cause irritation to the epithelial tissue of the user, particularly the skin and eye tissue.
- Various attempts have been made to mitigate the irritation of quaternary ammonium compounds to the skin and eye. Mitigants have included combining quaternary ammonium compounds with nonionic compounds, maltodextrin, urea, benzoate salts, and ethoxylated lanolin or alkoxylated fatty amines. Another mitigant found capable of decreasing irritation has been to combine quaternary ammonium compounds with mixtures of alkamine oxide surfactants with nonionic materials.
- While these mitigants provide some comfort to the consumer, a need exists for a phase stable, effective quaternary ammonium germicide that effectively and sufficiently reduces irritation to animal tissue, particularly skin and eye tissue.

In this test, hands of volunteers are inoculated with a volume of bacterial inoculum to constitute a bacterial challenge to the hands. The volunteers then wash their hands with the antibacterial composition to be tested, and this cycle is repeated 11 times. Bacterial reductions are determined after the first and eleventh wash.
- In this example, two exemplary formulations of antibacterial compositions were tested using the Health Care Personnel Hand Wash test. Hibiclens, a commercial product, serves as a positive control in the test. Table 1 summarizes the compositions of the formulations, Formulation 1 and 2.

Both formulations achieved log reductions of greater than 2 on the first wash and greater than 3 on the 11th wash. Additionally, both formulations exhibit superior antibacterial effectiveness as compared to the placebo. Thus, both formulations produce a preferred log reduction and provide sufficient performance.
- The reduced potential for eye irritation of various formulations of the compositions formed in accordance with the present invention was conducted using a Bovine Corneal Opacity and Permeability (BCOP) assay. The BCOP assay is known in the consumer products industry as an in vitro test for eye irritation potential. For surfactant-based formulations, the Permeability Value (PERMV) is also a measure of potential irritancy in the BCOP assay. Specifically, the Permeability Value is the Optical Density at 490 nm (OD490) determined with a spectrophotometer. It is used to measure the potential for eye irritation with higher irritation potential corresponding to higher Permeability Values. For personal cleansing compositions like liquid hand soaps, shower gels, and the like, an appropriate harsh control (control with high known potential for eye irritation) has a (PERMV) of 1 or higher. For example, a commercial liquid hand soap that is recognized as having potential for causing eye irritation has a (PERMV) of 1 to 1.125 in the BCOP assay. In general, compositions with PERMVs less than 1 are preferred in the art.
- In this example, various embodiments of antibacterial compositions were tested using the BCOP assay. Table 3 summarizes the base formulation used while varying the ratio of nonionic material to lauramine oxide and measuring the resulting PERMV score.

Lower lauramine oxide levels leads to lower PERMV, and hence lower eye irritation potential. Additionally, this example illustrates the surprising discovery that increasing the N:A ratio leads to lower PERMV, and hence decreasing eye irritation potential, especially for compositions with lower amounts of lauramine oxide.
- Table 5 summarizes the impact of the ratio of Pluronic F108 to lauramine oxide (N:A) on PERMI in the BCOP assay.

Surprisingly however, the PERMV scores, and the potential fore eye irritation, decrease strongly with increasing N:A, even for formulations with high lauramine oxide content. Without being limited by any particular theory, amine oxides appear to be the major determinants of irritation in formulations with quaternary ammonium germicides. Surprisingly, the ratio of nonionic material to amine oxide can be used to manipulate the irritation potential of formulations while maintaining antimicrobial efficacy at constant germicide concentration.
- Many modifications and variations of the invention as set forth can be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated by the appended claims.
